Webopedia Term of the Day: What is Google Chromecast?

A small WiFi-enabled dongle device that connects to a television via a HDMI port to wirelessly stream video and music content to the TV screen from smartphone (both Android and Apple iOS), tablet, laptop or desktop computer devices. Google Chromecast made its debut in late July, 2013, and retails for $35, which is considerably less expensive than the $99 Apple TV that Chromecast competes against.
